2 Claims. 01. 131-207 This inventionrelates to a filter holder for cigars and cigarettes and more particularly, to a specially configured, changeable filter cartridge and a complementary, permanent sheath tube.

According to the invention, there is provided an elongated filter cartridge which provides a tortuous absorbent path for smoke, and a sheath tube into which said filter cartridge may be inserted and from which it may be removed. The construction is such that smoke never comes into contact with the sheath tube and the entire device is simple and inexpensive and highly elficient in use.

In the accompanying drawing, Fig. 1 is a longitudinal sectional view of the outer sheath tube; Fig. 2 is a longitudinal section view through the filter cartridge; Fig. 3 is a transverse sectional view taken on line 33 of Fig. 2; and Fig. 4 is a longitudinal section view of the assembled sheath tube and filter cartridge and showing in broken lines a portion of a cigar or cigarette.

Referring to the drawing in detail, the filter cigarette holder is made up of a sheath tube a and a filter cartridge b; Filter cartridge b has a tapering body portion 16 .connected to a terminal portion b by means of a frusto- .conical connection portion 3. The terminal portion is ;provided with longitudinal grooves 4, 5 along its inner ;surface but terminating short of extremity 6. Numeral '7 represents the opening in the end of part 6 and is the (terminus of the bore in terminal portion b which is also :somewhat tapered toward extremity 6. At the end of body portion 16 remote from terminal portion b, the cartridge is of greater diameter to form an external step 14 defining an internal seat 12 and then the cartridge merges into the cylinder extension 2 whose wall is designated 15. There is a single diaphragm 11 on seat 12 and provided with perforations 13. Filtering granules 9 are disposed in the body portion 16, the connecting portion 3 and a part of the terminal portion b, the filtering granules being of such size that they cannot escape either through the perforations 13 or through the smallest end of terminal portion b. These filtering granules are maintained in a compacted condition by means of this single diaphragm, thereby forming a tortuous path for smoke passing through the cartridge, it being understood that the end of a cigarette or cigar 21 is inserted in the cylinder extension 2 and abutting the diaphragm 11. The other member of the invention, namely, the sheath tube a is complementary along its inner surface to the outer configurations of cartridge b and fits snugly in contact therewith as shown in Fig. 4 of the drawing. Surfaces 17 -;and 18 and the unnumbered connecting portion have the ;same conicity or taper as the corresponding parts of .cartn'dge b. The end 20 of a tube a abuts against step 14 and the mouth piece 1 with its opening 19 terminates fiush with the extremity six of terminal portion b. The

fit of tube a on cartridge b is also flush at the step 14.

A filter holder constructed in accordance with the in- --vention is highly advantageous due not only to its sim- -,-.-plicity and effectiveness but to its ability to render ciginjurious. The granules of filtering material extend throughout a major proportion of the length of the cartridge and are maintained in a compacted condition between the single perforate diaphragm and the taper of ithe bore taper of the terminal portion of the cartridge. The individual granules of the filtering materialare larger than the perforations in thediaphragm, and larger than the bore taper near the mouth piece end of the terminal portion of the cartridge, and hence, the granules cannot escape and force the smoke to take a long, tortuous path as it passes through the cartridge. The outer sheath 7 tube is unitaryand smooth-surfaced and is of 'a' permanent nature, composed of any suitable material which can be used with a plurality of successive filter cartridges. Each filter cartridge is so designed that it lasts for approximately one pack of cigarettes, after which it can be discarded and replaced by a fresh cartridge. An important feature of the invention resides in the fact that the outer sheath tube is always out of contact with smoke passing through the cartridge and out of contact with the filtering granules.

I claim:

1. A changeable filter cartridge for a holder for cigars and cigarettes consisting of an elongated, unitary, smooth-surfaced tubular body portion tapering toward a slender, open-ended, tapering tubular terminal portion and merging therewith by a frusto-conical connecting portion at their juncture, an internal and external step at the end of the body portion remote from said terminal portion, a cylindrical extension beyond said step for the reception of one end of a cigar or cigarette, said body portion and cylindrical extension being connected by said step which forms an annular seat at the juncture of said body portion and cylindrical extension, a perforate diaphragm in said cylindrical extension abutting said internal step and disposed on said annular seat, said terminal portion being provided on its inner surface with longitudinal smoke-conducting grooves terminating short of that extremity of said terminal opposite said frusto-conical connecting portion, and a mass of filtering granules filling said body portion, said frusto-conical connecting portion and the adjacent part of said terminal portion the individual granules of which are larger than the diaphragm perforations and the bore of the terminal portion adjacent the extremity thereof, whereby the diaphragm and the terminal portion form means for retaining the granules compacted in position to form a tortuous absorbent path for smoke passing through the cartridge and the construction being such that the smoke must pass only through the cartridge.

2. A changeable filter cartridge for a holder for cigars and cigarettes consisting of an elongated, unitary, smooth-surfaced tubular body portion tapering toward a slender, open-ended, tapering tubular terminal portion and merging therewith by a frusto-conical connecting portion at their juncture, an annular step forming an external abutment and an internal seat at the end of the body portion remote from said terminal portion, a cylindrical extension beyond said step for the reception of one end of a cigar or cigarette, said body portion and cylindrical extension being connected by said step, a perforate diaphragm in said cylindrical extension abutting said internal seat, said terminal portion being provided on its inner surface with longitudinal smoke-conducting grooves terminating short of that extremity of said terminal opposite said frusto-conical connecting portion, and a mass of filtering granules filling said body portion, said frusto conical connecting portion and the adjacent part of said terminal portion the individual granules of which are larger than the diaphragm perforations and the bore of the terminal portion adjacent the extremity thereof, whereby the diaphragm and the terminal portion form means for retaining the granules compacted in position to form :a tortuous absorbent path for smoke passing rthrou'gh the cartridge and the construction being such that the smoke must pass onlythrough the cartridge, and a permanent unitary, smooth-surfaced outer sheath tube internally shaped complementari'ly to said body and to said frusto-conical connecting portion and said terminal portion, the larger end of said sheath tube abutting said external abutment and the smaller end of said sheath tube terminating flush with said terminal portion to :form a mouthpiece, said outer tube beingalways out of-contact with said filtering granules and with smoke passing through said cartridge.
